Question

[4.90g" of potassium chlorate "(KClO_(3))" when heated produced "1.92g" of oxygen and the residue (KCI) left "],[" bettind weighed "2.96g" .Show that these results illustrate the law of conservation of mass."]​

Answer 1

Explanation:

given kclo3 reduced to O2 then mass left is 2.98

4.90-1.92=2.98 so the total mass of reactant is equal to product

thish shows law of conservation of mass
